Development environments for MongoDB drivers can be challenging to set up. The easiest way to work on swift-mongodb is to use Docker. This repository contains some configurations to help you get started.

# launch a cluster of Docker containers, each hosting a `mongod` instance
docker compose -f .github/mongonet/docker-compose.yml up -d
docker exec -t mongonet-mongo-0-1 /bin/mongosh --file /create-replica-set.js

Importantly, your own devcontainer must be connected to the cluster’s Docker network (mongonet).

services:
    your-vscode-container:
        image: your-devcontainer-image
        hostname: vscode
        networks:
            - mongonet

This library is Apache 2.0 licensed. It originally began as a re-write of MongoKitten by Joannis Orlandos and Robbert Brandsma.

All products depended-upon by this package are Foundation-free when compiled for a Linux target. Note that some package dependencies do vend products that import Foundation, but Swift links binaries at the product level, and this library does not depend on any such products.

Rarest packages:

1. gram

   Rationale: this package provides the TraceableErrors module which the driver uses to provide rich diagnostics. The driver does not depend on any parser targets.

2. h

   Rationale: this package implements cryptographic algorithms the driver uses to complete authentication with mongod/mongos servers.

Other packages:

1. apple/swift-collections

   Rationale: this package provides data structures that improve the runtime complexity of several algorithms the driver uses internally. Moreover, the driver’s swift-nio dependency already depends on one of this package’s modules (DequeModule) anyway.

2. apple/swift-nio

   Rationale: networking.

3. apple/swift-nio-ssl

   Rationale: networking.

Note: This library depends on the NIOSSL product from swift-nio-ssl, which imports Foundation on Apple platforms only. NIOSSL is Foundation-free on all other platforms.
